You have done all you can. Find your place of peace and pray for her. Letting go does not mean giving up. Perhaps with you out of the home, the authorities will step in and do what needs to be done. Please, do not berate yourself. This illness is wicked and unmerciful. I pray you live your life to the fullest in your new locale. God will watch out for you both. You can continue to love her from a distance. You do not have to endanger yourself to show love. Smell some roses, kick your feet in the ocean, watch the sunset. Live your life. In peace.
When you have the strength and will, perhaps you and the rest of us can band together to change the laws that fight against the caregivers causing more harm to families than good. Some laws work, others do not due to the lack of understanding related to this affliction. When someone with this dreaded disease commits a mass murder or some other heinous crime, that is all over the news. It is time for proactive education, not sensationalism that we so often see in the media regarding schizophrenia.
